I, Who Has a Crystal Core, Am Learning to Cultivate Immortality in the Last Days.

(The end of the world + rebirth + dual superpowers + cultivating immortals + hoarding supplies + decisive killing + establishing power) When the red meteor swarm descended, countless creatures mutated and became terrifying alien species, and civilization collapsed almost instantly. As a strong man with both strength and spirit, Qi Lin relied on his powerful strength to become the top master of Blue Star and was respected as the "Martial Emperor". But in order to become stronger, when he worked with other strong men to defeat a mutant that claimed to be a "divine beast", he was betrayed. When he opened his eyes again, he was actually reborn a month before the end of the world. He also got a magical crystal core from the alien beast, which also recorded the knowledge of cultivating immortals. Not only that, there was an infinite space inside the crystal core. In this life, Qi Lin will embark on the road of cultivating immortals, bringing his partners from his previous life to establish the strongest force in the last days. Qi Lin said that he will hoard supplies ruthlessly. There are also various medicinal materials. After all, if he can cultivate immortality, he can also make elixirs. He will become an immortal in this apocalyptic world, and will eventually be invincible in this world.
